A chart descriping the primitve data types available in Java. It shows in columns (from left to right) the keyword, range, type, and a descriptive example. It is based on the information from the Java tutorials[1] and format from Algorithms, 4th Edition.[2] Java Codings


From left to right, top to bottom the text reads

int, -2 to the 31st power to 2 to the 31st power - 1, 32-bit two's complement, Large whole numbers

long, -2 to the 63rd power to 2 to the 63rd power - 1, 64-bit two's complement, Very large whole numbers

float, See float, 32-bit IEEE 754 floating point, Decimals

double, See double, 64-bit IEEE 754 floating point, More precise decimals

boolean, true and false, 1-bit, not explicit, Conditions, flags
